i think the most people use the gtx 1070 for zcash mining. some people us the 1060 6gb cause they drain less power, so the sol/watt is better than the sol/watt of the 1070. but the 1070 perform better and have the higher resell value. here you have a calculator to see the difference:

im thinking about building a 6 gpu rig with 6x gtx 1080 ti, can anybody recommend me a psu wich is strong enough for that?

EVGA 1600 would do it and would be what I would recommend.

You'll need molex 4-pin or Sata risers though, won't have any PCIE left over to really run the risers unless you buy splitters but I wouldn't do that.

Why isnt 9x 8 pin sufficient ?

The GTX 1080 Ti takes 2 PCIE connectors per GPU, so you need 12 total for a 6 GPU rig. We have an EVGA 1600 watt PSU that just arrived today which I will be using for a new 6x GTX 1080 Ti rig once all the parts are here. ---- You can go with a 2 PSU set up also, ideally with 1 server PSU and an ATX PSU, probably the ideal setup. If you will have your rig mining in a living space though I personally can't stand the higher pitched noise of the server psu fans.... so for us (in a living space specifically) it was a no go this time around.

Our GTX 1080 Ti that I am testing/tweaking right now does ~603 Sols @ ~154 watts for an approximate 3.92 h/w efficiency. Pretty darned good in my humble opinion. It really cuts down on the heat too, running at a mere 61C with the fan at 50% on a reference cooler (FE model). An aftermarket cooler will do even better.

thanks for your reply. can you recommend me a mobo with 12 pcie slots for this case?

thanks in advance

PCIE connectors are the cables that plug into your video card, not the PCI-E slots on the motherboard. There isn't a 12 PCI-E slot motherboard on the market. Ones with 6 slots are rare enough, sometimes you will find one with 7 slots.

Was it a Motherboard with 6 PCI-E slots you needed or a Power Supply with 12 PCIE connectors? Or both?

Any socket 1150 Intel CPU will work for mining, even the cheapest Celeron. If you want to use the rig for office work, web browsing, streaming video/music while it mines then I suggest an i3 from that generation.

I like the R9 fury if you can get it for a deal. There for awhile they were 239. You can undervolt the hell out of them and still get 400 h. They can do more if you don't want to undervolt them. I have one running right now. 6 Cards and it fluctuates between 2400-2500 and uses 800-840 watts. I think I can get lower, but I'm using MSI AB and it only allows you to do -96mv. I'm going to try to do it manually on claymore to see if I can get a little bit more out of it. 750'ish would make me pretty happy.

Unless the hash rate is ridiculous and the numbers work out (hasn't been the case so far) - I don't like to go too much over $200. The 1080ti is great and has a ridiculous hash rate, but it's also ridiculously expensive and from a ROI standpoint, it doesn't make much sense to me. For some, maybe. That's just my opinion.

I have one Zotac mini 6gb-good card, but have tendency to heat up a little comparing with MSI 1080, which are rock solid at 500 without any tunung. Without any adjustment Zotac does 285mh on Linux. I am gearing up to do some power state improvement; no doubt they can do more.
